If you want to know how to work with those forked tube socket terminals it is actually not that hard. The secret is to use a solder sucker, which I do anyhow even in sets without the forked terminals, heat up the terminal, place the solder sucker on it once it's molten, then let go of the bulb or trigger. Sometimes you have to use it more then once, and that takes care of 90% of the old solder on the terminal. Then what you do is use a sharp, flat bladed, jeweler's screwdriver, a small one, to spread the fingers apart, sometimes heating up the joint again whilst you are at it, and the old component leads and wires will lift right out, replace in reverse order. I've worked on a lot of Canadian RCA and G.E sets from the late 1930s and early 40s, and they used the same forked terminals on the tube sockets as Ron's T7-5 uses, the American RCAs from that era did not according to what Ed Holland found in his RCA 110K2, so I had to work out a technique, no cutting and J hooking involved.
